WiFi not working with bcmwl-kernel-source on MacBook Air

in flag

From Additional Drivers, I enabled the bcmwl-kernel-source driver for BCM4360 802.11ac Wireless Network Adapter. I rebooted the computer. WiFi wasn't working. So I reinstalled bcmwl-kernel-source from command line. Still not working.

I'm using Ubuntu Cinnamon Remix 20.04.1

In command line, I had to install appropriate linux headers (with super user privileges):

apt-get install linux-headers-$(uname -r)

Then reinstall the driver (super user):

apt reinstall bcmwl-kernel-source

WiFi began to work instantly.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
